And for completeness, some statistics from the Consumer Products Safety Commission:
I’d hardly call that “nothing to worry about”.
Bolding mine.
Thanks for the info Q.E.D. did they specify what they are call “high voltage” it would take a long pole to come in contact with what we in the trade would call high voltage not to say it does not happen just that it is less likely.
As for the ladders this is again most likely a 120 volt shock, as the most common point of contact for a consumer will be an overhead service drop to a house.
No, they don’t specify, but given that in a typical US residential neighborhood the maximum one is likely to encounter is the pole-top 7,200 V lines, I’d say that’s what they are referring to.
How does an isolation transformer work to improve safety? I realize it eliminates the physical connection to ground, but its still got the full mains power coupled through it
No physical ground connection on the secondary side eliminates the possibility of a shock from the secondary live conductors and anything grounded.
You could still get a shock phase to phase, this system is used in some operating rooms and the like.
But they do require ground fault monitoring systems.
EEK!! Evidently I’ve been very lucky in my dealings with borrowed tools w/ frayed cords, and idiot assistants that don’t know which way is off on a circuit breaker.
Thank’s for educating me before I hurt myself.
My apologies for giving bad advice.
